Abstract
A 55-year-old male patient presenting with 6 months of bilateral difficulty in eye opening was referred to the ophthalmology department. Upon examination, multiple yellowish tumor-like plaques and nodules were observed on the eyelids and chest of the patient, accompanied by keratitis and iridocyclitis. Histopathological examination of the skin lesions on the chest revealed dermal xanthomatous granulomas with progressive necrosis. Bone marrow biopsy showed mantle cell lymphoma. Based on the medical history, the diagnosis of progressive necrotizing xanthogranuloma with mantle cell lymphoma was confirmed. After 6 months of treatment with bendamustine combined with rituximab, there was partial alleviation of ocular symptoms in the patient.

Abstract
Real-time monitoring of the development of atherosclerosis (AS) is key to the management of cardiovascular disease (CVD). However, existing laboratory approaches lack sensitivity and specificity, mostly due to the dearth of reliable AS biomarkers. Herein, we developed an in vivo fluorescent labeling strategy that allows specific staining of the foam cell-derived extracellular vesicles (EVs) in atherosclerotic plaques, which are released into the blood as circulating biomarkers for in vitro detection of AS. This strategy relies on a self-assembled nanoprobe that could recognize foam cells specifically, where the probe is degraded by the intracellular HClO to produce a trifluoromethyl-bearing boron-dipyrromethene fluorophore (termed B-CF3), a lipophilic dye that can be transferred to the exosomal membranes. These circulating B-CF3-stained EVs can be detected directly on a fluorescence spectrometer or microplate reader without resorting to any sophisticated analytical method. This liquid-biopsy format enables early detection and real-time differentiation of lesion vulnerability during AS progression, facilitating effective CVD management.

Abstract
OBJECTIVES This study aimed to explore occupational stress, perceived respect, and the need for psychological counselling among nurses in China. STUDY DESIGN This was a nationwide cross-sectional study. METHODS Chinese nurses from 311 cities were randomly selected through a simple random sampling method. Occupational stress, perceived respect, and psychological counselling need were assessed using an online questionnaire validated by experts. The underlying associated factors were analysed using multiple logistic regression analyses. RESULTS We collected and analysed 51,406 valid online questionnaires. Family factors and low income were the most commonly cited sources of occupational stress, and 91.9% and 80.0% of nurses, respectively, perceived that individuals in society and patients did not give adequate respect. Furthermore, 75.5% and 79.7%, respectively, believed they were not respected by clinical managers and doctors. As a result, 64.7% nurses believed they had a moderate or high need for psychological counselling. However, 80.7% indicated that receiving adequate respect could decrease the need for stress-related psychological counselling. Indeed, multiple logistic regression analyses showed that lower respect perceived by nurses was associated with higher need for psychological counselling, particularly regarding criticism that nurses perceived from nursing managers (a little: odds ratio [OR], 1.597; 95% confidence interval [CI], 1.176-2.170; P = 0.003; moderately: OR, 1.433; 95% CI, 1.180-1.741; P < 0.001) and the difficulty of receiving respect from patients and their families (a little: OR, 1.389; 95% CI, 1.044-1.850; P = 0.024). CONCLUSIONS Nurses in China perceive high levels of occupational stress and low levels of respect and often seek psychological counselling.

Abstract
A male patient presented to department of ophthalmology for progressive left eye blurred vision with visual deformation for 1 month. Imaging findings were typical intraocular lymphoma infiltration, and head MRI and positron emission tomography-CT showed no mass in other parts of the body. After review of the medical history, the patient first presented with extrocular signs such as lacrimal gland enlargement, eyeball protrusion and extraocular myoedema, without any abnormal changes in the fundus. Combined with the history, the patient was diagnosed as a binocular primary accessory mantle cell lymphoma with intraocular infiltration. After 9 months of systemic treatment with rituximab combined with zbrutinib, the patient's binocular visual acuity was significantly improved and the intraocular and intraocular manifestations disappeared.

Abstract
A large body of evidence indicates that long non-coding ribonucleic acid (lncRNA) is widely involved in various cellular processes and tumor progression. LINC00662, an lncRNA, has been reported to play a role in lung cancer. However, the biological function of LINC00662 in gastric cancer (GC) has not yet been explored. This study aimed to investigate the role and mechanisms of LINC00662 in promoting the proliferation, migration, and angiogenesis of BGC-823 and HGC-27 cells and the subsequent effect on the progression of GC. The expression level of LINC00662 in GC tissues and cells was detected by quantitative reverse transcription polymerase chain reaction. Small interfering RNA was used to silence LINC00662 in BGC-823 and HGC-27 GC cells in vitro for an MTT assay, a colony formation assay, and a transwell assay to determine cell proliferation and invasion ability. LINC00662-silenced BGC-823 and HGC-27 cells were also injected into zebrafish to detect the proliferation and invasion ability of the cells. Co-cultures in vitro of human umbilical vein endothelial cells (HUVECs) with silenced LINC00662 and in vivo experiments were also performed. The upregulation of LINC00662 was observed in GC tissues and cell lines. Functional studies in vitro showed that knocking down LINC00662 inhibited the proliferation and invasion of GC cells. In vivo experiments in zebrafish also confirmed that knocked-down LINC00662 inhibited the proliferation and invasion of GC cells, and in vitro angiogenesis experiments showed that the supernatant of GC with knocked-down LINC00662 inhibited the angiogenesis of HUVECs. LINC00662 promoted the proliferation, invasion, and migration of GC cells and promoted angiogenesis. These findings suggest that LINC00662 may be a potential therapeutic target for GC.

Abstract
Objective: To evaluate the safety and efficacy of a new domestic distal perforated stent graft (Talos stent) in the treatment of Stanford type B aortic dissection (TBAD). Methods: Twenty-five patients with TBAD treated with Talos stent in Yan'an Hospital Affiliated to Kunming Medical University from February 2018 to December 2019 were selected as the research subjects. Intraoperative angiography was performed to determine the number of branch arteries that remained after stent release. On postoperative day 5 (POD5), the pain intensity of the patients was evaluated by visual analog scale (VAS). The computed tomography angiography (CTA) of the patients before operation, 6 months and 12 months after operation were compared including aortic diameter, true lumen diameter, and false lumen diameter at the level of tracheal bifurcation. Follow-up was performed 1 month, 6 months, 12 months, and 24 months after surgery, and the occurrence of stent-related adverse events, reoperation and survival rate were recorded. Results: The enrolled patients included 19 males and 6 females, aged (52.6±11.1) years. Intraoperative angiography showed that 4 (1, 7) branch arteries were preserved, and the VAS score was 1 (0, 1) on POD5. The aortic diameters at the level of the tracheal bifurcation were (34.9±1.1) mm, (34.6±0.9) mm and (34.8±1.0) mm before surgery, 6 months and 12 months after surgery, and there was no significant difference (P=0.926); the diameters of the main true lumen at the level of the tracheal bifurcation were (13.3±1.6) mm, (21.8±1.0) mm and (22.3±1.1) mm before surgery, 6 months and 12 months postoperatively, while the diameters of the main false lumen at the level of the tracheal bifurcation were (20.8±2.2) mm, (4.5±1.5) mm, and (4.6±1.7) mm, respectively. Compared with before surgery, the diameter of true lumen increased significantly 6 months and 12 months after surgery (both P<0.001), while the diameter of false lumen decreased (both P<0.001). No stent-related adverse events occurred within 30 days after surgery, no secondary operations occurred within 12 months after surgery, no type Ⅰ and type Ⅲ endoleaks, no deaths or cases of paraplegia were reported, and the stent structure and position remained good. There were no deaths or paraplegia cases 24 months postoperatively, and no stent-related adverse events occurred. Conclusion: Using Talos stent in the treatment of TBAD can effectively help remodel the aorta, while preserve the intercostal artery and spinal artery, with good clinical effect and safety.

Abstract
The formation of atherosclerotic plaques is the root cause of various cardiovascular diseases (CVDs). Effective CVD interventions thus call for precise identification of the plaques to aid clinical assessment, diagnosis, and treatment of such diseases. In this study, we introduce a dual-target sequentially activated fluorescence reporting system, termed in-sequence high-specificity dual-reporter unlocking (iSHERLOCK), to precisely identify the atherosclerotic plaques in vivo and ex vivo. ISHERLOCK was achieved by creating a three-in-one fluorescent probe that permits highly specific and sensitive detection of lipid droplets and hypochlorous acid via "off-on" and ratiometric readouts, respectively. Based on this format, the upregulated lipid accumulation and oxidative stress-the two hallmarks of atherosclerosis (AS)-were specifically measured in the atherosclerotic plaques, breaking through the barrier of precise tissue biopsy of AS and thus aiding effective CVD stewardship.

Abstract
Objective: To investigate the effect of phacoemulsification on the Berger space (BS). Methods: A prospective cohort study. Patients with cataract who underwent phacoemulsification and intraocular lens implantation in the Department of Ophthalmology, Affiliated Hospital of Nantong University from May 2021 to October 2021 were enrolled. The BS was observed by slit-lamp microscopy and anterior segment optical coherence tomography (AS-OCT) before and 1 month after operation. Intraoperative optical coherence tomography with a 25G optical fiber was performed to observe the BS. The number of eyes with the BS and materials in the BS (MIB) detected perioperatively was counted, and the width of the BS was measured. Statistical analysis was carried out by the Chi-square test, generalized estimating equations, Mann-Whitney U test and binary logistic regression analysis. Results: A total of 119 patients (119 eyes) were included [44 males, 75 females; mean age, (65±12) years]. Preoperatively, the BS was identified in only 4 eyes (3.4%), and no MIB was found. Intraoperatively, the BS was identified in 47 eyes (39.5%), and the MIB was observed in 20 eyes (16.8%). At one month postoperatively, the BS was identified in 33 eyes (27.7%), of which 16 eyes (13.4%) still had MIB. There were significant differences in the detection rates of the BS and MIB between intraoperative and preoperative groups (both P<0.001). The difference in the detection rate of the BS postoperatively compared to intraoperatively was statistically significant (P=0.001), while the difference in the detection rate of MIB was not statistically significant (P>0.05). The intraoperative and postoperative width of the BS [M (Q1, Q3)] was 160.3 (61.6, 273.1) μm and 106.8 (0, 259.4) μm, respectively, and the difference was statistically significant (Z=-2.28, P=0.023). In addition, the detection rate of the BS and MIB in patients with a high risk of zonular fiber weakness [60.7% (17/28) and 42.9% (12/28)] was significantly higher than that in patients without this risk factor [33.0% (30/91) and 8.8% (8/91)] (χ²=6.90, P=0.009; P<0.001). In the multivariable model, weakness of zonular fibers (OR=0.214, 95%CI: 0.081 to 0.561) and higher cumulative dissipated energy (OR=1.255, 95%CI: 1.047 to 1.504) were the main risk factors for structural changes of the BS intraoperatively. Conclusion: Phacoemulsification can damage the normal anatomical structure of the BS, resulting in intraoperative entrance of fluid and particulates to the BS.

Abstract
The aim of this study was to investigate the preventive effect of pancreatic duct stent on acute pancreatitis after endoscopic retrograde cholangiopancreatography. A retrospective analysis of the case data of patients who first underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis in the Beijing Friendship Hospital from January 2015 to December 2019 for 5 years. According to whether the pancreatic duct stent was indwelled during the operation, they were divided into pancreatic duct stent group (147 cases) and non-indwelling pancreatic duct stent group (192 cases). The incidence of acute pancreatitis after endoscopic retrograde cholangiopancreatography was compared between the two groups according to COTTON criteria. Independent sample t test, Pearson Chi-square test (χ2) and Fisher's exact test were used to compare groups' differences. There were 2 cases of acute pancreatitis in the pancreatic duct stent group, all of which improved after 48 hours. There were 22 cases of acute pancreatitis in the non-indwelling pancreatic duct stent group, of which 20 cases improved within 48 hours, and the other 2 cases had severe pancreatitis, which improved and discharged after 30 days of treatment. There was significant difference in the incidence of acute pancreatitis between the pancreatic duct stenting group (1.4%) and the group without placement of pancreatic duct stents (11.5%) (χ²=12.905,P<0.001). In conclusion, Pancreatic duct stent may be an effective method to prevent PEP.

Abstract
Objective: To evaluate the diagnostic value of bronchoalveolar lavage fluid pathogen detection combined with cryptococcal antigen test(CrAg) for pulmonary cryptococcosis(PC). Methods: A retrospective case analysis was performed on non-acquired immunodeficiency syndrome patients admitted to Ninghai First Hospital for suspected PC from January 2018 to December 2019. Fifty-nine patients were included. Sixteen cases (8 males and 8 females) were diagnosed with PC, aged from 18 to 76 years[an average age of (52±14) years], while 43 cases were diagnosed as having Non-PC. All patients had undergone both serum CrAg test and BALF pathogen detection(cultures and direct examination) combined with BALF-CrAg test. The sensitivity and specificity of the combined method of BALF was evaluated, and a parallel comparison of the diagnostic efficiencies of the two methods were made. Results: Of the 16 confirmed PC cases, serum CrAg tests were positive in 11 and negative in 5 cases, while the combined method showed that 14 were positive and 2 were negative. Compared with the clinical final diagnosis, the sensitivity, specificity, positive predictive value and negative predictive value showed that the serum CrAg tests were 68.8% (11/16), 97.7% (42/43), 91.7% (11/12), 89.3% (42/47) respectively, versus 87.5% (14/16), 100.0% (43/43), 100% (14/14), 95.6% (43/45) by the combined method of BALF. The results displayed no statistical difference between the two diagnostic methods (P =1.000). Among the 5 initially serum CrAg-negative cases, 4 were later confirmed as proven PC via the combined method of BALF and the other one by percutaneous lung biopsy. Conclusion: The combined method of BALF pathogen detection with BALF-CrAg showed a similar statistical efficiency rate for diagnosing pulmonary cryptococcosis compared with serum CrAg tests. It may serve as an efficient diagnosis method for PC cases with negative serum CrAg tests.

Abstract
Precursor messenger RNA (pre-mRNA) splicing is critical for cell growth and development, and errors in RNA splicing frequently cause cellular dysfunction, abnormal gene expression, and a variety of human diseases. However, there is currently a lack of reliable systems to noninvasively monitor the mRNA splicing efficiency in cells and animals. Here, we described the design of a genetically engineered ratiometric dual luciferase reporter to continuously quantify the changes in mRNA splice variants in vivo. This reporter system is encoded within a single polypeptide but on separate exons, thus generating two distinct luciferase signals derived from spliced and unspliced mRNAs. With this reporter, the two kinds of luciferase in the same individual can minimize the influence of indirect factors on splicing, and the ratio of these two luciferase intensities represents the dynamic splicing efficiency of pre-mRNA. Our study offers a convenient and robust tool for the screening and identification of small molecules or trans-acting factors that affect the efficiency of specific splicing reactions.

Abstract
Extruded potato (P) and sweet potato (SP) products with red palm oil (RPO) were prepared under different conditions. Superior product characteristics such as sensory score, expansion ratio, and water solubility index, among others, were obtained at high extrusion temperature (150-155 °C) and low water feed rate to the extruder (50.4-50.8 mL/min). The optimal products, P1 and SP1, had high micronutrients as their total contents of β-carotene, squalene, tocopherols, and tocotrienols were 883.2, 304.4, 262.4, and 397.0 mg/kg of oil, respectively. The average peroxide value was 4.3 meq O2/kg oil, p-anisidine value 3.3, and induction period (100 °C) 11.4 h. Moreover, RPO extruded with P showed a better extrusion behavior but lower micronutrient retention and oxidative stability than that extruded with SP. Thus, the finding herein is important for investigating extrusion conditions, increasing variety, improving nutritional quality, assessing applicability and predicting the shelf-life of RPO-P/SP-extruded food.

Abstract
Objective: To investigate the occurrence and influencing factors of perioperative complications after robotic gynecologic surgery. Methods: The clinical data and occurrence of perioperative complications in 1 000 cases robotic surgery completed in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Results: (1) Clinical data: the average age of the patients was (50.2±10.4) years old, and the average body mass index (BMI) was (24.4±3.6) kg/m2. Among 1 000 cases, 811 cases of them were malignant tumors, including 405 cases of cervical cancer, 279 cases of endometrial carcinoma, 112 cases of epithelial ovarian cancer (EOC), 15 cases of vulvar cancer; 189 cases of them were benign diseases, including 43 cases of uterine prolapse, 57 cases hysterectomy of uterine leiomyoma and adenomyosis of the uterus ≥12 weeks, 84 cases myomectomy of uterine leiomyoma, and 5 cases of fallopian tubal ligation requiring anastomosis. Surgical methods: in patients with malignant tumors, cervical cancer, hysterectomy plus salpingectomy or salpingo-oophorectomy for stage Ⅰa1, and radical hysterectomy plus pelvic lymphatic dissection plus salpingectomy or salpingo-oophorectomy for stage Ⅰa2-Ⅱb. Endometrial carcinoma, performed by staging surgery. Staging surgery for EOC with early stage and cytoreductive surgery with advanced EOC. Vulvar cancer, extensive vulvar resection plus inguinal lymphadenectomy. In patients with benign diseases, uterine prolapse, hysterectomy plus salpingectomy or salpingo-oophorectomy plus sacrocolpopexy. Uterine leiomyoma or adenomyosis with uterus ≥ 12 weeks, hysterectomy plus salpingectomy or salpingo-oophorectomy. Myomectomy for patients requiring uterine preservation with uterine leiomyoma. Tubal anastomosis for patients with fallopian tubal ligation. (2) Surgical complications: intraoperative complications occurred in 25 patients (2.5%, 25/1 000), including 11 patients with vascular laceration, 11 patients with ureteral injury, 2 patients with bladder injury, and 1 patient with intestinal injury. Postoperative complications occurred in 130 patients (13.0%, 130/1 000), including 66 cases of lower limb venous thrombosis, 20 cases of lymphatic cyst, 8 cases of hydronephrosis, 9 cases of ileus, 16 cases with infection, 6 cases with genital fistula, 4 cases with trocar site herniation and 1 case with subcutaneous emphysema. The incidence of intraoperative complications was 3.1% (25/811) in malignant tumors and no case in benign diseases, the incidence rate in malignant tumors was significantly higher than that in benign diseases (χ²=4.778, P=0.029). The incidence rate in cervical cancer (4.2%, 17/405) and EOC (3.6%, 4/112) were significantly higher than those in endometrial carcinoma (1.4%, 4/279) and vulvar cancer (0/15; P<0.05). The incidence of postoperative complications was 15.2% (123/811) in malignant tumors and 3.7% (7/189) in benign diseases. The incidence rate in malignant tumors was significantly higher than that in benign diseases (χ²=17.807, P<0.01), but there were no significant difference among different malignant tumors (χ²=4.318, P=0.229). (3) The correlative factors affecting the occurrence of surgical complications: patient's age, BMI, previous pelvic or abdominal surgery history, the nature of disease (malignant or benign), operation time, and comorbidities had a significant impact on the incidence of postoperative complications (P<0.05). Multivariate logistic regression analysis showed that the patient's age ≥40 years old, BMI ≥25 kg/m2, previous pelvic or abdominal surgery history, malignant tumors and comorbidities were independent influential factors of the postoperative complications (P<0.05). Conclusions: Perioperative complications vary according to the type of the surgery. The age, BMI, previous pelvic or abdominal surgery history, malignant tumors, and comorbidities are influential factors of postoperative complications.

Abstract
Pyroptotic cell death is a phenomenon that runs through all life activities and plays an important role in physiological and pathological processes of the body's metabolism. It is of big biological significance to understand the phenomenon and nature of cell pyroptosis. In the process of cell pyroptosis, the pore-forming effector gasdermin D (GSDMD) is cleaved to form oligomers, which are inserted into the cell membrane, causing rapid cell death. However, the effective cell death induced by GSDMD complicates our ability to understand the behavior of pyroptosis. In this work, we performed molecular mutagenesis to develop a genetically encoded pyroptotic reporter, where a secreted Gaussia luciferase (Gluc) was strategically placed in the p30-p20 tolerated junction of GSDMD to support natural pyrophosphorylation and promote live imaging of cell pyroptosis. In addition, we demonstrated that this fused Gluc-GSDMD reporter executed inflammatory body-dependent pyroptosis in response to extracellular stimuli, and that the lysed p30-GSDMD can be secreted out of the cell and can be detected in the culture medium and animal blood. Therefore, our study provides a valuable tool that not only noninvasive and real-time monitoring of cell pyroptosis, but also affords a high-throughput functional screening of pyroptosis-targeted compounds in cultured cells and animal models.

Abstract
Past firefighting water additives were found to contain perfluorinated compounds that could persist in the environment resulting in potential adverse effects to biota. Since this revelation, manufacturers have introduced alternative firefighting water additives that are fluorine free, but few studies have investigated the fate and effects in the environment of these new additives. Firefighting water additives could enter aquatic ecosystems through run-off, leaching or direct application. Therefore, there is a need to investigate the potential effect that firefighting water additives could have on aquatic biota. This study investigated the toxicity of six firefighting water additives: Eco-Gel™, Thermo-Gel™, FireAde™, Fire-Brake™, Novacool Foam™, and F-500™ to aquatic biota. The toxicities of firefighting water additives to Lemna minor (duckweed), Daphnia magna (water flea), Hexagenia spp. larvae (mayfly), Lampsilis fasciola (wavy-rayed lampmussel) and Oncorhynchus mykiss (rainbow trout) were investigated through acute and chronic static and semi-static tests to estimate LC50 values for survival and EC50 values for immobility and/or reproduction endpoints. A large variation in toxicities among the firefighting water additives and among the test species was observed. Based on a worst-case exposure scenario of direct application, several firefighting water additives were found to pose a hazard to aquatic organisms. An exposure rate representative of a direct overhead application by a water bomber during a forest fire was used in the hazard assessment. For example, the hazard quotients determined for the D. magna acute toxicity tests ranged from 0.20 for Eco-Gel to 317 for F-500 in the forest pool (15 cm) scenario. This study presents the first deterministic risk assessment of firefighting water additives in aquatic ecosystems.

Abstract
Objective: To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 (lymph-vascular space invasion-positive, LVSI+)- Ⅰb1 cervical cancer patients with different tumor sizes. Methods: Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results: (1) A total of 4 891 patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.367, 95%CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups (94.1% vs 95.4%, P=0.151). While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS (HR=1.420, 95%CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS (P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups (P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.705, 95%CI: 1.088-2.674, P=0.020). Conclusions: For patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.

Abstract
CONTEXT As a part of interstellar dust, polycyclic aromatic hydrocarbons (PAHs) are processed by the interaction with vacuum ultra-violet (VUV) photons that are emitted by hot young stars. This interaction leads to the emission of the well-known aromatic infrared bands but also of electrons, which can significantly contribute to the heating of the interstellar gas. AIMS Our aim is to investigate the impact of molecular size on the photoionization properties of cationic PAHs. METHODS Trapped PAH cations of sizes between 30 and 48 carbon atoms were submitted to VUV photons in the range of 9 to 20 eV from the DESIRS beamline at the synchrotron SOLEIL. All resulting photoproducts including dications and fragment cations were mass-analyzed and recorded as a function of photon energy. RESULTS Photoionization is found to be predominant over dissociation at all energies, which differs from an earlier study on smaller PAHs. The photoionization branching ratio reaches 0.98 at 20 eV for the largest studied PAH. The photoionization threshold is observed to be between 9.1 and 10.2 eV, in agreement with the evolution of the ionization potential with size. Ionization cross sections were indirectly obtained and photoionization yields extracted from their ratio with theoretical photoabsorption cross sections, which were calculated using time-dependent density functional theory. An analytical function was derived to calculate this yield for a given molecular size. CONCLUSIONS Large PAH cations could be efficiently ionized in H i regions and provide a contribution to the heating of the gas by photoelectric effect. Also, at the border of or in H ii regions, PAHs could be exposed to photons of energy higher than 13.6 eV. Our work provides recipes to be used in astronomical models to quantify these points.

Abstract
AIM Quinoline is a recalcitrant pollutant in coking wastewater which has been broadly investigated with many isolates possessing aerobic quinoline-degrading ability. However, studies on anaerobic degradation and the corresponding bacteria are very scarce. This study attempted to investigate the role of diverse functional members and the redundancy of quinoline degradation in a lab-scale quinoline denitrifying bioreactor. METHODS AND RESULTS Antibiotics were added to the batch culture under denitrifying conditions to disturb the microbial community of the quinoline-degrading bioreactor. According to the results, the nitrate removal rate remained stable, and the quinoline removal rate increased by 9·7% after treatment with streptomycin. However, PCoA analysis of 16S rRNA gene sequencing data of these samples indicated a significant shift in microbial community structures. Specifically, 12 operational taxonomic units (OTUs), including OTU1 (Pseudomonas) and OTU2 (Achromobacter), were significantly enriched. OTU1 replaced OTU8 (Thauera) as the most predominant denitrifying quinoline-degrading member. However, OTU8 and other predominant OTUs (Comamonas and Pseudoxanthomonas), which were hypothesized to contribute essentially to quinoline degradation in the origin bioreactor, became almost undetectable. CONCLUSION Functional redundancy due to high biological diversity allowed the role reversal of predominant quinoline-degrading bacteria and other rare bacteria when disturbed by antibiotic stress. Although the abundance of OTU1 was much lower initially, it replaced the essential role of the predominant member OTU8 in the bioreactor community for quinoline degradation once the environmental condition changed. SIGNIFICANCE AND IMPACT OF THE STUDY This study indicated that the high biological diversity in a wastewater treatment bacterial community is crucial for maintaining the degrading function of organic pollutants, especially in a changing environment due to external disturbance or stress.

Abstract
PURPOSE To explore the concentration of squamous cell carcinoma antigen (SCCA), cytokeratin fragment antigen 21-1 (CYFRA21-1) in patients with laryngeal squamous cell carcinoma (LSCC) and its correlation with tumorigenesis and progression. METHODS A total of 78 patients with LSCC admitted to our hospital from February 2010 to January 2016 were enrolled as the research group (RG), and another 41 healthy volunteers from the same period were selected as the control group (CG). The serum concentrations of SCCA and CYFRA21-1 in patients with LSCC were detected by ELISA, whose diagnostic value in LSCC were further analyzed by ROC curve. The prognosis and survival curves of patients with LSCC were observed according to the median value of serum SCCA and CYFRA21-1 concentrations. RESULTS The concentration of CYFRA21-1 and SCCA in the RG was significantly higher than that in the CG (p < 0.050). The SCCA and CYFRA21-1 identified a significant difference in smoking, lymphatic metastasis, TNM staging, and differentiation degree (p < 0.050). The survival rate of the SCCA low-concentration group was significantly better than that of the high-concentration group, p < 0.050. The survival rate of the CYFRA21-1 low-concentration group was markedly better than that of the high-concentration group, p < 0.050. CONCLUSIONS SCCA and CYFRA21-1 are highly concentrated in LSCC patients, which have good diagnostic efficacy for LSCC. In addition, they play some certain role in the occurrence and development of LSCC, and are expected to be markers for early diagnosis and prognosis of this disease.

Abstract
Abstract
Introduction
The purpose of this study is to report 5 consecutive days’ descriptive data for sleep efficiency (SE), total sleep time (TST), and daytime activity ratio (DAR) among critically ill mechanically ventilated adults from 9 intensive care units (ICU) across two hospitals. To our knowledge, this is the first study to describe sleep and activity patterns among mechanically ventilated adults during the early critical illness period.
Methods
We enrolled 31 critically ill mechanically ventilated subjects within 48 hours of ICU admission. Daytime periods were defined as 06:00-21:59; nighttime periods were defined as 22:00-05:59. Actigraphy estimated nighttime SE, TST, and the DAR. We calculated mean DARs [DAR = (daytime activity count per minute / 24-hour activity count per minute) x 100], which may be an indicator of altered rest/activity cycles. In our study, a DAR of >80% was used to define normal rest/activity patterns. Descriptive analyses were used for this sub-analysis of our parent randomized controlled trial.
Results
Among the 31 subjects included, the mean age was 59.6 ± 17.3 years, 41.9% were male, 80.6% were White, and 67.7% were Hispanic/Latino. The mean nighttime SE and TST over the 5-day ICU period were 83.1% ± 16.1 and 6.6 ± 1.3 hours, respectively. The mean DAR over the 5-day ICU period was 66.5% ± 19.2. Only 17.5% of subject days (14 days out of a total of 80 recorded days) met the definition of normal rest/activity patterns (DAR >80%).
Conclusion
Throughout the early ICU period, among mechanically ventilated patients, both the sleep/wake as well as the rest/activity cycle were disturbed. Intervention studies targeting the optimization of nighttime sleep consolidation and daytime activity should be investigated.
Support
This project was supported by a federal grant from the National Institutes of Health/National Institute of Nursing Research (R01NR016702). This clinical trial is registered with ClinicalTrials.gov (NCT03128671).

Abstract
OBJECTIVE Many studies have recently suggested that dendritic cell (DC) vaccine contributes to the immunotherapy of various types of human tumors. It has been proved that the tumor antigen sensitizing and the gene silencing are effective methods for the preparation of the DC vaccines. The aim of this study is to investigate the specific anti-laryngocarcinoma immune response for the suppression of cytokine signaling1 (SOCS1) silencing and Hep-2 sensitizing DC. MATERIALS AND METHODS The dendritic cells derived from peripheral blood mononuclear cells were induced by cytokines GM-CSF, IL-4, and TNF-α in vitro, and the morphological characteristics of dendritic cells were observed under a microscope, indicating that they successfully differentiated into dendritic cells. The RNA interference vector was used to transfect dendritic cells. The expression of SOCS1 was detected by Western blot and the effective target sequence for inhibiting the expression of SOCS1 was screened. The expressions of CD83, CD86, and HLA-DR on dendritic cells were detected by flow cytometry. The content of IFN-γ in the supernatant was analyzed by enzyme-linked immunosorbent assay (ELISA). Methyl thiazolyl tetrazolium (MTT) was used to evaluate the ability of dendritic cells to stimulate T cell proliferation and induce the killing activity of cytotoxic T cells. RESULTS The result of PCR and Western blot analysis shows that the expression of SOCS1 significantly decreased under the influence of the 5th interference sequence. The flow cytometric analysis results show that SOCS1 silencing and Hep-2 sensitizing dendritic cells had high expressions of CD83 (85.61±0.96)%, CD86 (96.86±1.20)%, and HLA-DR (98.02±0.94)%. The DC vaccine could increase the production of IFN-γ according to the ELISA assay results. The MTT assay results show that the DC vaccine could also stimulate the proliferation of the T cells and effectively and eventually enhance the specific killing effect of CTL. CONCLUSIONS SOCS1 silencing and Hep-2 sensitizing DC vaccine could induce an effective and specific anti-laryngocarcinoma immune response.

Abstract
BACKGROUND AND PURPOSE Acidification of the tumor microenvironment from abnormal metabolism along with angiogenesis to meet metabolic demands are both hallmarks of malignant brain tumors; however, the interdependency of tumor acidity and vascularity has not been explored. Therefore, our aim was to investigate the association between pH-sensitive amine chemical exchange saturation transfer echoplanar imaging (CEST-EPI) and relative cerebral blood volume (CBV) measurements obtained from dynamic susceptibility contrast (DSC) perfusion MRI in patients with gliomas. MATERIALS AND METHODS In this retrospective study, 90 patients with histologically confirmed gliomas were scanned between 2015 and 2018 (median age, 50.3 years; male/female ratio = 59:31). pH-weighting was obtained using chemical exchange saturation transfer echo-planar imaging estimation of the magnetization transfer ratio asymmetry at 3 ppm, and CBV was estimated using DSC-MR imaging. The voxelwise correlation and patient-wise median value correlation between the magnetization transfer ratio asymmetry at 3 ppm and CBV within T2-hyperintense lesions and contrast-enhancing lesions were evaluated using the Pearson correlation analysis. RESULTS General colocalization of elevated perfusion and high acidity was observed in tumors, with local intratumor heterogeneity. For patient-wise analysis, median CBV and magnetization transfer ratio asymmetry at 3 ppm within T2-hyperintense lesions were significantly correlated (R = 0.3180, P = .002), but not in areas of contrast enhancement (P = .52). The positive correlation in T2-hyperintense lesions remained within high-grade gliomas (R = 0.4128, P = .001) and in isocitrate dehydrogenase wild-type gliomas (R = 0.4300, P = .002), but not in World Health Organization II or in isocitrate dehydrogenase mutant tumors. Both magnetization transfer ratio asymmetry at 3 ppm and the voxelwise correlation between magnetization transfer ratio asymmetry and CBV were higher in high-grade gliomas compared with low-grade gliomas in T2-hyperintense tumors (magnetization transfer ratio asymmetry, P = .02; Pearson correlation, P = .01). The same trend held when comparing isocitrate dehydrogenase wild-type gliomas and isocitrate dehydrogenase mutant gliomas (magnetization transfer ratio asymmetry, P = .04; Pearson correlation, P = .01). CONCLUSIONS A positive linear correlation between CBV and acidity in areas of T2-hyperintense, nonenhancing tumor, but not enhancing tumor, was observed across patients. Local heterogeneity was observed within individual tumors.

Abstract
A novel heterogeneous catalyst, the ionic liquid (IL) of 1-butyl-3-methylimidazolium acetate (BmimOAc) immobilized on MIL-101-NH2, denoted as IL(OAc-)-MIL-101-NH2, was prepared by the "ship-in-a-bottle" strategy. The IL of BmimOAc was prepared in the MIL-101-NH2 nanocages primordially, in which the condensation product of MIL-101-NH2's amine group with 1,1'-carbonyldiimidazole (CDI) reacted with 1-bromo butane, and then the intermediate exchanged with potassium acetate. The structure and physicochemical properties of IL(OAc-)-MIL-101-NH2 were characterized by powder X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, DRS UV-vis, nitrogen adsorption-desorption, and elemental analysis. The results indicated that BmimOAc was anchored in the MIL-101-NH2 skeleton via the acylamino group and confined in the nanocages in the form of a single molecule. The composite material of IL(OAc-)-MIL-101-NH2 exhibited excellent catalytic activity and catalytically synthesized 3-aryl-2-oxazolone in an excellent yield of 92%. It can be reused up to six times without noteworthy loss of its activity and demonstrated distinct size-selective property for substrates. It was conjectured that the diffusion kinetics of reactants could be controlled by the aperture size of the metal-organic framework support.

Abstract
BACKGROUND Pre-operative tissue diagnosis for suspected malignant biliary strictures remains challenging. AIM To develop evidence-based consensus statements on endoscopic tissue acquisition for biliary strictures. METHODS The initial draft of statements was prepared following a systematic literature review. A committee of 20 experts from Asia-Pacific region then reviewed, discussed, and modified the statements. Two rounds of independent voting were conducted to reach a final version. Consensus was considered to be achieved when 80% or more of voting members voted "agree completely" or "agree with some reservation." RESULTS Eleven statements achieved consensus. The choice of tissue sampling modalities for biliary strictures depends on the clinical setting, the location of lesion, and availability of expertise. Detailed radiological and endoscopic evaluation is useful to guide the selection of appropriate tissue acquisition technique. Standard intraductal biliary brushing and/or forceps biopsy is the first option when endoscopic biliary drainage is required with an overall (range) sensitivity and specificity of 45% (26%-72%) and 99% (98%-100%), and 48% (15%-100%) and 99% (97%-100%), respectively, in diagnosing malignant biliary strictures. Probe-based confocal laser endomicroscopy and fluorescence in situ hybridisation using 4 fluorescent-labelled probes targeting chromosomes 3, 7, 17 and 9p21 locus may be added to improve the diagnostic yield. Cholangioscopy-guided biopsy and EUS-guided tissue acquisition can be considered after prior negative conventional tissue sampling with an overall (range) sensitivity and specificity of 60% (38%-88%) and 98% (83%-100%), and 80% (46%-100%) and 97% (92%-100%), respectively, in diagnosing malignant biliary strictures. CONCLUSION These consensus statements provide evidence-based recommendations for endoscopic tissue acquisition of biliary strictures.

Abstract
People's health behaviours and outcomes can be profoundly shaped by the social networks they are embedded in. Based on graph theory, social network analysis is a research framework for the study of social interactions and the structure of these interactions among social actors. A literature search was conducted in PubMed and Web of Science for articles published until August 2017 that applied social network analysis to examine obesity and social networks. Eight studies (three cross-sectional and five longitudinal) conducted in the US (n = 6) and Australia (n = 2) were identified. Seven focused on adolescents' and one on adults' friendship networks. They examined structural features of these networks that were associated with obesity, including degree distribution, popularity, modularity maximization and K-clique percolation. All three cross-sectional studies that used exponential random graph models found individuals with similar body weight status and/or weight-related behaviour were more likely to share a network tie than individuals with dissimilar traits. Three longitudinal studies using stochastic actor-based models found friendship network characteristics influenced change in individuals' body weight status and/or weight-related behaviour over time. Future research should focus on diverse populations and types of social networks and identifying the mechanisms by which social networks influence obesity to inform network-based interventions.

Abstract
Anthropometric measures are simple, inexpensive, noninvasive tools to assess the risk of morbidity and mortality. This systematic review assessed the performance of A Body Shape Index (ABSI) in predicting hypertension, cardiovascular disease, type 2 diabetes and all-cause mortality and compared the differential predictability between ABSI and two other common anthropometric measures - body mass index and waist circumference. A keyword and reference search were conducted in the PubMed and Web of Science for articles published until 1 November 2017. Thirty-eight studies were included in the review, including 24 retrospective cohort studies and 14 cross-sectional studies conducted in 15 countries. Meta-analysis found that a standard deviation increase in ABSI was associated with an increase in the odds of hypertension by 13% and type 2 diabetes by 35% and an increase in cardiovascular disease risk by 21% and all-cause mortality risk by 55%. ABSI outperformed body mass index and waist circumference in predicting all-cause mortality but underperformed in predicting chronic diseases. ABSI is highly clustered around the mean with a rather small variance, making it difficult to define a clinical cutoff for clinical practice. Future studies are warranted to assess ABSI's potential usefulness as an anthropometric measure in population-level health surveillance.

Abstract
Global warming and the obesity epidemic are two unprecedented challenges mankind faces today. A literature search was conducted in the PubMed, Web of Science, EBSCO and Scopus for articles published until July 2017 that reported findings on the relationship between global warming and the obesity epidemic. Fifty studies were identified. Topic-wise, articles were classified into four relationships - global warming and the obesity epidemic are correlated because of common drivers (n = 21); global warming influences the obesity epidemic (n = 13); the obesity epidemic influences global warming (n = 13); and global warming and the obesity epidemic influence each other (n = 3). We constructed a conceptual model linking global warming and the obesity epidemic - the fossil fuel economy, population growth and industrialization impact land use and urbanization, motorized transportation and agricultural productivity and consequently influences global warming by excess greenhouse gas emission and the obesity epidemic by nutrition transition and physical inactivity; global warming also directly impacts obesity by food supply/price shock and adaptive thermogenesis, and the obesity epidemic impacts global warming by the elevated energy consumption. Policies that endorse deployment of clean and sustainable energy sources, and urban designs that promote active lifestyles, are likely to alleviate the societal burden of global warming and obesity.

Abstract
Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM. Therefore, the aim of this study is to evaluate the feasibility of the 1940 nm thulium laser in POEM. From March 2015 to August 2015, five patients with achalasia at the Digestive department, Beijing Friendship Hospital, Capital Medical University, Beijing, China were included. Before the procedure, the patients' gender, age, and duration of symptoms were recorded. Eckardt symptom score and LES thickness, which measured by endoscopic ultrasonography, were recorded. While the subtypes of achalasia (according to the Chicago classification), lower esophagus sphincter resting pressure (LESRP) and integrated relaxation pressure (IRP) were measured by HRM for all patients. Barium esophagram was also used to rule out anatomical lesions, esophageal varices, or neoplasia, which may cause similar symptoms. All examinations were performed one week before POEM. POEM was performed with the 1940 nm thulium laser under general anesthesia. Eckardt score, procedure duration, myotomy length, and complications were recorded one week after POEM. All the patients were followed-up at two weeks and four weeks after POEM. POEM was successfully performed in all five patients. The mean age of the patients was 38.8 years (24-54 years). Achalasia subtypes were type I (n = 1), II (n = 2), and III (n = 2). The operation duration was 186, 180, 111, 75, and 126 minutes for the five cases. Pre/postprocedure Eckardt scores were 3/0, 7/0, 5/1, 6/0, and 9/0. Pre/postprocedure LESRP (mmHg) were 45.3/26.4, 18.0/1.1, 25.8/10.4, 16.5/11.2, and 24.2/20.8. Pre/postprocedure IRP (mmHg) were 27.3/15.5, 15.4/4.2, 5.7/6.8, 15.5/10.1, and 13.1/14, respectively. No adverse events occurred during the procedure. After POEM, subcutaneous emphysema occurred in case 1 on the first day, which relieved spontaneously after two days without special intervention. Infection occurred in case 5 on the day of POEM was healed with antibiotics three days later. The 1940 nm thulium laser is feasible for POEM procedure. Further studies are needed to determine whether the 1940 nm thulium laser is better than high-frequency electrotome.

Abstract
Objective: To study the effects of simulating leg length inequality on the spine and pelvic posture in standing and walking states and to explore their compensatory laws. Methods: From January to April, a total of 44 healthy volunteers were rasterstereographically examined for spine and pelvis in Institute of Digitized Medicine, Wenzhou Medical University and Department of Orthopaedics, First Affiliated Hospital of Wenzhou Medical University.Volunteers wore uniform shoes, and single 5 mm thick insoles were customized.The simulating leg length inequalities (5-30 mm) were artificially created by increasing insole height.The parameters of 3D body surface parameters and 4D dynamic parameters of the pelvic and spine were measured and statistically analyzed in standing and walking states. Results: In the static standing state, with the increase of the difference of both lower extremities, coronal plane pelvic tilt and sagittal plane pelvic torsion also increased[the maximum value about (10.6±4.3) mm and (3.3±3.5)°], as well as the frontal deviation of the spine [the maximum value about (11.1±17.9) mm]. But the pelvic rotation, vertebral surface rotation angle (rms) and spine sagittal plane deviation were no obvious changes.In the walking state, with the difference between lower extremities increased, the maximum angles of vertebral surface rotation to the left and right and pelvic rotation to the left and right were no obvious changes, but (coronal) spinal maximum offset distance to left and right increased [the maximum value about (9.8±5.1), (10.4±6.9) mm]. Conclusion: The effect of the leg length discrepancy on the pelvic coronal plane and the sagittal plane changes are obvious, but little effect has on the pelvic cross section.The pelvis is compensated by the increase of the inclination of the coronal plane and the sagittal angle at first order.Similarly, the effect on the coronal plane of the spine is more markedly, but the changes of sagittal and cross-section of the spine is less affected, the spine is mainly compensated by the coronal plane bending at second order.

Abstract
Objective: To investigate the associations between various blood test parameters including MLR (monocyte-lymphocyte ratio) and prognosis in post-operative esophagogastric junction cancer patients. Methods: We retrospectively studied the preoperative and postoperative data of 309 patients who underwent radical surgery for esophagogastric junction cancer. The relationship between MLR, neutrophil lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and overall survival (OS) was analyzed. Results: The cutoff values of MLR、NLR and PLR were 0.201, 1.697 and 96.960, respectively. The median OS was 51.4 months for all the patients in the study group (n=309). MLR in patients with esophagogastric junction carcinoma was associated with gender, depth of invasion, histological grade, TNM stage, NLR and PLR (P<0.05). PLR was associated with tumor size, TNM stage, NLR and MLR (P<0.05). NLR was associated with gender, tumor size, TNM stage, PLR and MLR (both P<0.05). Univariate analysis showed that tumor size, depth of tumor invasion, metastasis of lymph nodes, pathological grading, nerve infiltration, lymphovascular invasion, TNM staging, PLR and MLR were associated with the median overall survival time (P<0.05). Multivariate analysis showed that TNM stage, nerve infiltration and MLR were independent prognostic predictors for patients with esophagogastric junction cancer (P<0.05), but not PLR or NLR. Setting the optimal cut-off value of the MLR in 0.201, the area under the curve was 0.603, significantly larger than that of PLR and NLR (P<0.05). Conclusions: Preoperative MLR is a very useful predictor of patients with esophagogastric junction cancer who underwent radical rescetion. Preoperative MLR> 0.201 is an independent risk factor for postoperative survival in patients with esophagogastric cancer, and PLR> 96.960 may predict a poor prognosis risk.
